……这里），微积分方面，推荐同一作者的《No BS Guide to Math/Physics》。这两本书都包含了我正需要的高中数学复习（比如三角函数）。至于微分方程（DiffEq），我现在推荐 Logan 的《微分方程初级教程》（A First Course in Differential Equations），我现在就学到这儿，在试了 r/math 推荐的几本教材后，我发现这本是最温和易懂的。背景信息：我是个成年人，拿的是 20 年前的工程学学位。
…here), and for calculus, "No BS Guide to Math/Physics" by the same author. These books both include a review of high school math (i.e. trig) which i needed. For DiffEq I currently recommend Logan's "A First Course in Differential Equations", this is where I am now and I found this the most gentle after trying several textbooks recommended from r/math. Context: I am an adult with an engineering degree from 20 yrs ago.
…ideas are built on understanding the previous ideas first), you can self-study a lot of mathematics. But almost everyone (mathematicians, physicists, engineers) who has that maturity, has probably taken a first course in differential equations during their undergrad studies. So the number of people who have developed some mathematical maturity without ever taking a diff.eq. course is probably small. So we don't know much about these people…

……思想都是先建立在理解前置思想的基础之上的），你可以自学大量的数学。但几乎每个具备这种数学成熟度的人（数学家、物理学家、工程师），在本科期间大概都学过微分方程入门课。所以，从未上过微分方程（diff.eq.）课却具备一定数学成熟度的人可能凤毛麟角。因此我们对这群人知之甚少……
